* doc/whatsnew.txt
  * include/hbextern.ch
  * source/vm/runner.c
  * source/rdd/dbcmd.c
    * __HRB*() functions marked as HB_LEGACY_LEVEL2 compatibility,
      please update your code to use HB_HRB*().
    * __RDDGETTEMPALIAS() marked as HB_LEGACY_LEVEL2 compatibility,
      please update your code to use HB_RDDGETTEMPALIAS().
    ; I've permanently remove these symbols from hbextern.ch, so 
      regardless of the legacy setting, hbrun won't have them 
      anymore. This is merely technical, as it would need some 
      hacks in the make system to push through HB_LEGACY_OFF 
      to pptable.c generation. If someone wants to deal with 
      this, even better.

  * include/hbstdgen.ch
    * Added #undef __FILE__.

  * include/hbsetup.ch
    * Minor.
